Understanding the rules before a medical cannabis appointment can help you ask better questions and avoid preventable risks. This guide explains the steps from a clinical consultation to document checks and checkout. It is written for adults 20 and over. A prescription does not make cannabis risk-free, and this article does not replace individual medical or legal advice.

1. Understand the prescription requirement

Thailand regulates cannabis flower for medical use. Official guidance requires a valid cannabis prescription and limits dispensing to the quantity medically necessary, up to a 30-day supply. Tourists should obtain advice from an appropriately licensed practitioner in Thailand rather than assume an overseas prescription is accepted. A displayed product or an open shop is not proof that a purchase is lawful.

Online cannabis sales and vending-machine sales are prohibited under the official guidance. Treat checkout as the final step after the required checks, rather than an online shopping shortcut. See the Thai government's notice for visitors. The government's 22 October 2026 policy update also reiterates the medical-use focus.

2. Prepare for the consultation

Bring valid photo identification and any existing prescription or relevant medical documents. Ask the provider which documents are required before your appointment. Prepare a list of your medicines, supplements, allergies and previous reactions to cannabis.

Explain your symptoms honestly, including their duration and any treatment you have already tried. Tell the clinician about pregnancy or breastfeeding, heart problems, anxiety, panic, psychosis or other mental health history, and alcohol or sedative use. These details can affect whether cannabis is appropriate.

3. Let the clinician assess suitability

A consultation is an assessment, not a promise of a prescription. Ask about expected benefits, uncertainties, side effects, interactions and alternatives. If cannabis is prescribed, make sure you understand the product, route of use, instructions, treatment duration and follow-up plan. Ask questions before leaving if any instruction is unclear.

4. Complete the checks before checkout

At an authorised dispensing premises, staff should check your identification and prescription before dispensing. Confirm the product and quantity match the prescription. Ask to see the premises' current authorisation and request clear product information, including available batch or testing details.

Before payment, confirm the total cost, instructions, storage requirements and how to contact the dispensing team with questions. Keep the receipt, original packaging and prescription documentation. Do not share prescribed cannabis with another person or assume that permission to obtain it also permits public consumption or travel across a border.

5. Plan for safety after the appointment

Use only as directed by your licensed clinician. Do not drive or operate machinery after use; arrange suitable transport in advance. Combining cannabis with alcohol can increase impairment. Ask your clinician about interactions with medicines, especially sedatives.

Avoid cannabis during pregnancy or breastfeeding. Cannabis can affect thinking, coordination and mental health, and smoking can harm the lungs. Store any prescribed product securely, away from children and pets. Contact a healthcare professional about unwanted effects or concerns, and seek urgent medical help for severe symptoms.
